= SMS and calls theory =
If the incoming SMS delivery calls have a caller ID in the [https://www.bt.com/content/dam/bt/help/legacy-ug/new-pdf/BT%20SMS%20Text%20service%20centre%20numbers.pdf BT Text], the chances are there that it understands [https://www.etsi.org/deliver/etsi_es/201900_201999/201912/ ETSI ES 201 912], and for incoming SMS, refers to the caller as the SM-SC and recipient as SM-TE, or use the implementation [https://wiki.asterisk.org/wiki/display/AST/Application_SMS in Asterisk]
# the SM-SC, hopefully, detects it is talking to an SM-TE rather than a person, and cancels any text-to-speech, once successful confirmation is obtained according to the protocol then call recording can stop and any recording discarded.
# receive the SMS, it can then be logged digitally if the customer wants that, leaving the communication channel open for the next steps if required to deliver confirmation the message has reached its destination
# if the real terminal equipment, with the internet suggesting that Gigaset devices
# The message can also or instead be transferred via a variety of other methods, without analogue emulation, such as [https://

Trying to send SMS from Vodafone to a BT number ported to AAISP does result in text-to-speech calls that come from 08456021111, which is different from the numbers in gigaset [https://gse.gigaset.com/fileadmin/legacy-assets/CustomerCare/Manuals/SL4xx/SL450_GO/A31008-M2721-L101-1-7619_en_IE-UK.pdf sl450a-go] that is use to get calls, so there likely be no need to support both the text to speech and FSK based SMS delivery.
The factory numbers are 1470P17094009* to send (as in active send=yes) and 0800587529* to receive (as in active send=no), it can be set to process these numbers on IP1 instead of "Fixed"
The asterisk apparently means to accept any follow-on digits, although it could mean asterisk literally also.
Therefore, the outstanding matters are to get BT to send AAISP SMS either via [https://www.bt.com/help/landline/set-up-and-use-bt-text SMS over PSTN], (by us [sending "register" to 00000 or BT delivering SMS over inter-operator transports such as text files over ftp over ipsec.

= Block SMS text to speech =
The user may prefer to lose incoming SMS completely than have them delivered as voice calls, such as where the ability to intercept calls from +448456021111 and +443333440000 to voicemail is not set up.
To do that the opt-out functions are used on both [https://www.bt.com/help/landline/set-up-and-use-bt-text BT] and [https://aql.com/aqltext/ AQL], with both pages used to opt back in later, such as to do further tests if progress on inbound digital delivery of SMS is known about.
